We need to extend the valves for our inner duallies. I guess there are two basic options -- braided or straight. We intend to add TST 507 TPMS. Any thought about these:

They come in 2, 3 and 4 inch lengths.

I found this thread below using the search function. All the replies in the thread have meaningful information. As you will read in the thread I have the steel braided extenders on the inside duel tires and the fill end is attached securely to the outside hub for easy access and no flopping around. These were on the coach when I purchased it just over three years ago and I have not had a problem with them. I use the Pressure Pro TPMS. It interfaces with the Silverleaf which shows all twelve tires' pressures in a rotating format (coach - 8 and toad - 4). The problem with Pressure Pro is their batteries are not changeable. I have to get new "senders" which attach to the valve stems when the batteries get low - cost $30 to $35 each.

Larry,
I like the straight ones. They don't need to be supported as the braided ones do. Used them on our last 2 coaches with no issues. Simply loosen the nut on the existing stem and turn it so it is facing outboard, re-tighten and screw on the extenders. (Be sure the existing stem will clear the wheel opening to point outboard before buying the straight ones).

As well as using the straight steel extenders, install rubber support grommets in the appropriate wheel hole to support the weight of the extender and the sender- this stops centrifugal force stressing the valve stem seal where it enters the wheel.

WE had Pete's Tire/Towing remove the old flex units with the solid extenders and gromets, the whole thing looks better because they are better.

Friends ...
Thanks for the good suggestions. We have a well-regarded truck tire company in my town and I'm going to reach out to them tomorrow to see if they can set me up properly.

I purchased some rather spendy extenders when I had new tires put on a couple years ago at Dickman's (Les Schwab in Junction City Oregon). I don't remember the product name, but it did include the grommet and angled stems on the outer tires and longer ones coming through from the inner tires. I also put the same TST flow through monitoring system on mine. From time to time I've had these monitors stop working, and have had to remove them, and reset them (is the best way I have found) by simply removing or if the battery is low, replacing the battery. I also didn't install any of the rubber O-rings that were sent with the kit, but found eventually that my driver's side front monitor stopped working, so I took it off, noted some signs of water ingress, put the O-ring in and it worked again so I've since removed all the monitors opened them up and put the O-ring in. I guess you should too unless yours already have O-rings in them. Mine did not.
Another thing I have noticed is that the flow through valves are not as easy to get air into as simply removing the monitors and filling directly to the valve stems. Also be careful that you screw the in tightly enough but not too tightly as either condition can cause them not to work correctly and even leak.
